BRAKE-HANGER BRACKET.

Application filed February 17, 1923. Serial No. 619,776.

To all w/iomv it may com-ern.:

Be it known that I, Bruns FV. Kamin, a citizen of the United States, residing at Baltimore, in the State of liaryland, have invented certain new and useful Improven'ients in Brake-Hanger Brackets; and I do hereby declare the following to be a full, clear, and eXact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to car trucks and more particularly to a brake hanger bracket oi' carrier.

rl'he principal feature of the invention, generally stated, resides in the provision of a strong, durable and efficient brake hanger bracket formed with a plurality of connecting portions advantageously located with respect to the main supporting web of the bracket, said connecting portions being also arranged for engagement with. the adjacentportions of the truck columns and compression member of the side frame.

Particularly stated, the invention consists in providing a brake hanger bracket adapted for attachment to a wrought metal side frame wherein it is desirable to rigidly support the brake hanger bracket and mount the brake hangers within the standard A. R. A. limits, and at the same time provide for sufficient clearance between the bolster and bracket.

Another object of the invention is to provide a brake hanger bracket including a plate portion and projecting channel-shaped web, the latter being provided with an extending triini'iion located adjacent an opening in the web whereby the looped supporting end of the brake hanger is rmounted relatively close to the bolster opening and is permitted to move within said opening clear of any contact with the said web.

A furtherfeature of the invention is to provide a brake hanger bracket composed of an attaching plate portion and an inwardly extending brake hanger supporting portion, said supporting portion including a vertically disposed web having a cut away portion therein, a projection extending from one side of the web toward the bolster opening with which the bolster may contact, and mea-ns extending from the opposite side of said web adjacent said cut away portion for supporting the hanger with its looped end extending into said cut away portion.

The invention further consists in arranging the vertically disposed web of the brake hanger supporting portion and reinforcing the saine by continuing portions thereof about an attaching point ofthe bracket and` otherwise reinforcing the supporting web with relation to other of the attaching portions. l j

With these and other objects in view, the invention further consists in the combination, construction and arrangementof the several parts hereinafter 'described and pointed out in the claims.

In the drawings: y Y

Figure l is a side view of my improved brake hanger bracket shown attached to a portion of a car truck side frame, portions of the bolster and brake hanger being shown in dotted lines.

Figure 2 is a detached view illustrating in side elevation the opposite side of the brake hanger.

Figure 3 isan end view of the bracket shown attached to a portion of the side frame and illustrating the looped ends of the brake hanger attachedthereto.

Figure l is a plan view of the bracket shown in Figure 3, a portion of the bolster being illustrated to emphasize the clearance between one face of the bracket and said bolster. v

Figure 5 is4 a horizontal sectional view taken on the line 5 5 of 4Figure 3. Y

Referring to the drawings wherein similar reference characters Adesignate corresponding parts in the several views, my improved construction of brake hanger bracket is shown attached to the side frame l, the latter involving the usual compression member n 2, truck columns 3 and tension member-'4. Pedestal tie bar portions 5 may also be provided, all of said parts being'disposed in the usual vmanner with relation to the bolster opening 6, portions of the bolster being indicated in dotted lines in` some of the views.

My present construction of brake hanger'` bracket includes a base or attaching plate portion 7 having an intermediate offset portion 7 preferably suitably spaced from the side wall of the side frame, as shown in Figure 3. The upper part of the'iplate attaching portion 7 is providedwith a plurality of openings 8 adapted to receive connecting` rivets S). The rivet openings are preferably" y formed lin thickened port-ions l0 of the plate section and are disposed upon.A either.. side of the vertical .reinforcing rib 111 extending inwardly of the side frame. The rib 11 serves to unite the upper portionof the plate lsection 7 witlithe upper part ofthe brake hanger supporting portion ofthe bracket to be presently described. The loiverportlon of the plate section 7 is provided with an opening 12, s aid opei'iingv being. adaptedito. receive one of the rivets 9. The rivet opening 12 is preferablylocatedv adjacentl a strong portion-of the truck column, that is to say, the lowermostv attachingportion,ofy the ,bracketl islocated'below the4 nari-Qwest portion of'- said;t ruck column-,porti(. n. In addition, the lowerinostrivet opening` 12 is preferably disposed longitudinally intermediate the rivet openings S in the upper part of the plate section` of theI bracket, said rivet openings Sbeing preferably arranged adj acent relatively large cross lsectional areasA ofthe compression member 2.

The brake hangerattaching portion of lthe`V bracket involves a cbannelshaped portion consisting. ofthe vertically disposed gweb 13, an upper-'flange 1st,y and a lower flan-gelo, both of said flanges projecting away from.l the bolster, andthe lowermost. of ,said flan-ges being smaller and arranged to underlie the uppermost ofsaid .ianges Projecting from the vertical web 13iare integral= extensions 16 and 17, said extensions being suitably reinforcedand otherwise, disposed to form the trunnilons which receive. the.. hanger pin. rlhe` pin` isshown at 18 in dotted lines in. Eig-ure. 3 i as supporting, i the brake hanger and linore( especially` the.,ar1ns 19 thereof, the usual washers 22. and cottel. pinv 23 being ,also illustrated byidotted lines.

'The vertical web 13 of thehanger:sup-` porting portion of the bracket is provided with an opening orapertureQG, said opening extending above and below the: center line of the hanger pin .zand being arranged adjacent the tiflinnion..extension .16. In my, present embodiment lrhave shown an. elongate/.l aperture, although` it will be under;v stood that variousl otherforms of cut-away portions, openings, slots, and vsliapings may. be used to effect ythe clearance of theupper looped .end ofthe brake hanger arm supported adjacent the trunnionI 1G. Upon `the face of the web 13 adjacent the bolster and more especially withingthe limits rof. movement of the cover plate thereof, isprovided a ,bead orl )ro'ectino' )o rtion- Qlil said bead in addition to.strengtheningthe metal.i immediately adjacent. said opening` being.. also adapted toreceive,andindicate the wear as imparted` to the brake .hanger bracket` fronrthe bolster cover plate. Bythis, means of tell-tale yportion or bead ,foi-mation,v it, will be seen that observations of the wear can be noted from timer to timeas affecting 1 the service reoluireinentsdemanded of "these:

andother associated portionsot the equipment. By means of cutting, awayL portions of the web 13 it will be seen that the center of support of the brake hangers can be maintained within y standard j limitations an d at the same time the full'supporting strength of the bracket, and especially of said web, can be utilized, it also being observed that by thisconstruction maximum clearance between the bolster and brake hanger bracket is maintained.

The vertical web.l3 at its lower end is preferably continuedf around a portion, of the rivet opening l2, said rivet openingbeing preferably located-toene sideofythe centerofsaid web. One.of;the rivet;open-y ings 8 vin `the upperx part-p ofthe,` plate attache ing portion is located uponl the` opposite: si de:l of avertical centen passingthrouglr the web 13.V The arrangement;offthese attach ingportions ofthe, bracket upon Asubstantially opposite .sides of thefvertieeliweb; sup; porting the trunnions, acts to provide; a very@ strongand effective connection, it-beingtobserved thatfwhile said connectingrivets are vertically-offset, the, amountof-said offset is` relatively slight and somewhat dependent upon. the thickness and.;disposition ofthe vertical web. The offset arrangement ofithe reinforcing rib, 11 with respect to thel verticalweb l 13,.` and its intermediate location between the rivetspassing through theopene ings 3, serves tofcomiplement; theuvertical; supporting strength; of the, bracketiiir` beamlike.. action through@ v the upper flange A11i e of A the channel-shaped brake hangerlsupport-g ing -portionr-vofgt-l'ie bracket.
